Question 286 · LDEK · Benign tumors
Depending on the extent of infiltration, ameloblastoma classified as B3 is a tumor located:
- A. intraosseous with perforation of lamina dura, intact periosteum, in the medial area of mandible, not exceeding the line of both canines.
- B. intraosseous with perforation of lamina dura and periosteum and soft tissue infiltration, occupying one or two anterior or two posterior quadrants of both jaws.
- C. completely intraosseous, with no perforation of lamina dura, unilaterally in the mandible ramus and body, not exceeding the canine line on the same side.
- D. intraosseous with perforation of lamina dura and periosteum, no soft tissue infiltration, occupying half of the mandible (ramus, body), exceeding the central line, but not exceeding the line of canine on the opposite side.
- E. intraosseous with perforation of lamina dura, occupying two quadrants of the same jaw (anterior and posterior).
Hint
Decode the code: the letter grades depth of infiltration (cortex, periosteum, soft tissue), the number grades extent across quadrants.
